Description

  The present invention relates to an electric gate capable of self-propelling on a guide rail, and more particularly to a moving column structure incorporating various functions required for the electric gate.

  In recent years, electric gates have been widely adopted for gates installed at wide gates in factories, etc., where a motor is provided on the door body and the wheels are driven by this motor so that it can run on the guide rail. It became so.

  In general, such electric gates are provided with a suspension column on one side of the gate and a door column on the other side, and a guide rail is provided between the suspension column and the door column. Laid. A door body that travels on the guide rail is attached to the suspension base column, and this door body is provided with a suspension base fixed column that is attached to the suspension base column at one end and is moved to the door at the other end. A column is provided, and a telescopic door body having a pantograph mechanism is provided between the suspension fixed column and the door-to-door moving column.

  By the way, as such an electric gate, a technique has been proposed in which a motor and a driving vehicle are provided on a movable rod and power is supplied to the motor from a battery provided on a fixed rod via a pantograph mechanism (for example, see Patent Document 1). .

  In addition, a technique has been proposed in which a door controller is provided with a power supply unit, a speed controller that controls the rotation of the motor motor steplessly, a sequencer receiving antenna, and the like (see, for example, Patent Document 2 and Patent Document 3). .

  Furthermore, a technique has been proposed in which power is supplied to the motor by providing a rechargeable battery on the door itself, rather than supplying power by a wiring cord or the like. That is, by providing the electric motor device, the storage battery device, and the terminal for charging on the traveling platform provided at the moving side end of the door body, the terminal for the general AC power supply is provided on the door-to-door pillar, and both terminals are brought into contact with each other.

Via the rechargeable battery 110 to be charged. The rechargeable battery 110 outputs 12V DC power and is supplied to the motor 160 and the like.

  Next, the opening / closing operation of the gate will be described with reference to FIGS.

First, the opening operation will be described. Gates is in the fully closed state to open the gates from the closed state, as shown in FIG. 13, and instructs the opening operation of t ₀ at gates, the central processing unit 71, a motor 160 closing direction The door-to-door movement column 42 is pressed against the door-to-door support column 10 by rotating at a constant speed in the direction of the door-to-door support column, and the solenoid 102 is turned on to raise the lock pin 101 and release the lock. Further, the sensor power supply is turned on so that the fixed position sensor 81 and the slow sensor 82 can be detected, and the fixed position sensor 81 detects the closed-side fixed position plate 151.

Next, when a preset time elapses and t ₁ o'clock is reached, the motor 160 is rotated in the reverse direction so as to gradually increase in speed in the opening direction to perform slow-up running. Therefore, the door-to-door movement column 42 moves away from the door-to-door support column 10 and moves toward the suspension column 20. Due to the movement of the door-to-door moving column 42, the fixed position sensor 81 is separated from the closed-side fixed position plate 151 and is turned off. Next, the slow sensor 82 detects the closed side slow plate 152 and is turned on. Then, when the door-to-door moving column 42 further advances and the slow sensor 82 is turned off at the time t ₂ , the rotation of the motor 160 is maintained at the speed at that time. Becomes constant speed running. At this time, the solenoid 102 is turned off, and the lock pin 101 is projected.

Doorstop mobile column 42 is close to the hanging original strut 20 continues to constant speed running, if t ₃ during the slow sensor 82 detects the open side throw plate 154, gradually dropping slow down the running speed of the motor 160. Then, when the door-to-door moving column 42 further advances and the home position sensor 81 detects the open side home plate 153, the motor 160 is stopped. As a result, the door-to-door moving column 42 stops at the open position, and the opening operation is completed.

Incidentally, in order to perform the opening operation from when the doorstop mobile column 42 is positioned in the middle of the guide rail 30, predetermined as shown in FIG. 14, at t _0:00 which instructs to perform the opening operation, the solenoid 102 The lock pin 101 is pulled up for a period of time and the sensor power supply is turned on, and the subsequent operation is the same.

Next, the closing operation will be described. Gates is in the fully open state and close the gates from the open state, as shown in FIG. 15, and instructs the opening operation of t ₀ at gates, the central processing unit 71, the solenoid 102 a predetermined time on to The lock pin 101 is pulled up for a certain time. Further, the sensor power supply is turned on so that the fixed position sensor 81 and the slow sensor 82 can be detected, and the fixed position sensor 81 detects the open-side fixed position plate 153 and is turned on. Then, at time t _1, it is gradually rotated while increasing the speed of the motor 160 to move the doorstop mobile column 42. Then, t ₂ at the slow sensor 82 detects the open side throw plate 154 shifts to constant-speed running from the slow-up driving to a speed of the motor 160 constant.

When the door-to-door moving column 42 continues to run at a constant speed and approaches the door-to-door support column 10, when the slow sensor 82 detects the closing side slow plate 152 at t ₃ , the speed of the motor 160 is gradually reduced and the motor is slowed down. The solenoid 102 is turned on and the lock pin 101 is pulled up. Then, further progressed doorstop mobile column 42, when t ₄ o'clock position sensor 81 detects the open side position plate 151, gradually increasing the speed of the motor 160 slows up running, the doorstop mobile column 42 door It is pressed against the contact strut 10 and then stopped. As a result, the door-to-door moving column 42 stops at the closed position, and the closing operation is completed.

In order to perform the closing operation when the door-to-door moving column 42 is located in the middle of the guide rail 30, as shown in FIG. 16, the solenoid 102 is turned on at time t ₀ when an instruction to perform the closing operation is issued. Then, the lock pin 101 is pulled up, and the state is maintained until the closing operation is completed, and the subsequent operation is the same.
